摘要
随着经济社会发展和城镇化、机动化进程的不断加快,特别是我国公路基础设施网络近年来快速发展和网络化迅速形成,影响道路交通安全的因素突然增多,有的未得到有效解决,我国现处于道路交通事故的高发期,安全隐患呈上升趋势,道路交通事故死亡人数总量仍然很大,万车死亡率处于较高水平,群死群伤特大恶性事故时有发生,事故预防、预警预报和应急救援手段相对滞后于工作的需要,存在很大的道路交通事故反弹压力。山体滑坡、滚石伤害、隧道坍塌落石和桥梁倒塌等道路交通事故已成为危害人民群众生命财产安全,影响社会和谐稳定的重要因素之一。
     安全监测已由过去的人工用肉眼、皮尺量测等简易监测,发展到仪器仪表监测,现正逐步实现自动化、高精度的遥测系统,具体包括统一地理信息系统下的道路边坡防护、桥梁防护、隧道防护、山体防护、道路基础设施防偷盗防护和防雷抗浪涌防护等统一平台的安全防护综合性管控。国内外大量工程和运营管理实践表明,利用高精度传感系统对交通工程和设施进行全面的综合监测和监控,是保证工程和运营安全运行的重要措施之一。综合性主动式安全防护是国际上交通安全管理控制的发展前沿。
     本文基于实时无线传感网络,对高速公路山体及桥隧安全监测系统进行了研究。
     (1)设计了系统地总体技术方案,构建了主动式安全防护平台。系统设计同时注重管理机构的服务水平和运营能力,系统的推动运营将根据情况实现不同的盈利,实现最佳的社会效益和经济效益。推动安全、节能和高效的可持续良性循环发展。
     (2)分别对主动式安全防护平台中各个子系统:传感监测系统、视频监控系统、无线通信传输系统、数据采集系统、数据及信息管理系统等进行了方案设计、传感器选型、系统开发等工作,确保了各子系统所采用技术的可靠性以及各子系统之间的兼容性。
     (3)在小盘岭隧道、高速公路沿线和山体施工现场进行了实地测试,验证了基于实时无线传感网络系统在实际工作环境下的安全监测功能。确定了系统的功能、性能、安全性和可靠性,为确定吉林高速公路山体及桥隧安全监测系统解决方案的技术标准提供了依据。
     通过科学实践的实证证明:精确化、全移动、可视化的系统机制对于交通基础设施安全管理、监测预警防护和紧急指挥处理更贴近行业实际需求和科学化特征,结合快速反应无须人为干预的公众出行服务辅助系统支持将构建先进而标准化并且具有科学方法论支持的安全管理体系。安全管理重在三个及时,即及时预测、及时发现、及时处理,对于管理机构的执法和管理依据起到更加明确、直观和及时准确的作用。全移动同步的安全监管有效提高行业管理效率、减少盲区,促使枯燥的管理向人性化、直观化、轻松日常化方向发展。
With economic and social development and urbanization, a motorized progress has been accelerated, and especially our road infrastructure network of the recent rapid development and quickly into the net impact on the road traffic safety factors suddenly increased, some have no effective solution .Our country is now in the road traffic accidents period, the rising, and the deaths of the traffic accident is still very strong, and the mortality rate in higher level and extraordinarily big accidents occur malignant. Accident prevention, early warning forecast and emergency rescue measures are needed to lag behind the work, there is a lot of road traffic accidents on the rebound. Landslides, the rolling stones injuries, the tunnel collapsed bridge collapses for falling rocks and road traffic accidents has become a threat to the people's lives and property security, social harmony and stability of the major factor.
     Safe monitoring with the naked eye, a simple test for monitoring the development of the instruments that are being progressively implement automation, high precision telemetry systems. Specifically includes the road slopes protection, bridges protection, tunnel protection, mountain protection, road infrastructure against stealing protection and against the thunder and waves protection. They are dependent on the unified platform of the security guard comprehensive control which is integrated into the geographical information system. A lot of projects and operations management practice shows that the use of high precision sensing system to a comprehensive traffic and facilities of the integrated monitoring and control, is one of significant measures which ensure construction and operation to work safety. Comprehensive active security guard is in the frontier of traffic safety administration of the control in international.
     Author studied safety monitoring system of the highway including tunnels and neighboring mountains in this paper based on real-time wireless sensor network.
     (1) Designed the overall and systematical technical solutions and built active security guard platform. While attach importance to systematically design, emphasis on operational capability and service level of administration. According to circumstances, systematical promoted business, so that realize profit, the best social and economic returns and promote the sustainable development of benign cycle which is safe, efficient and energy-efficient.
     (2) Security guard platforms include sensing monitoring system, video surveillance systems, wireless communications transport systems, data collection systems and data and information management system. Author worked on design, sensors sizing, systems development of these systems to ensure that the system adopted by the technical reliability and compatibility between the subsystem.
     (3) Author has tested the real-time wireless networks sensing in the tunnels through small hill, highway and construction site validating the function of safety monitoring in the real work conditions and setting the system functions and performance, security and reliability. Provide the basis for determining technical standards of solutions of safety monitoring system of mountain and tunnel concerning road.
     Scientific practice proved system mechanism of precision, full mobility, visualization more close to actual needs and scientific characteristics. With the rapid reaction without artificial intervention of the public service system will travel to support the establishment of the advanced and standardization and scientific methodology has the support of the security management system. Security management shows three timely:
     Timely forecast, timely discovery, timely handle. The law enforcement and management of administration play more clear, visual and precise role. Mobile synchronization security supervision improve management efficiency of enterprise, reduce dead zone and promoted the tedious management to aim to developing humanization visualize and generalization.
